Include self-selection in composite portfolios. Composite portfolios contain work by more than one student and can be used for many different purposes. As with any portfolio, the overall goal is to demonstrate student learning. A composite portfolio might be one way to demonstrate what impact a school or program is having on students in general, to demonstrate what is being taught, or as a learning tool for groups of students. Student contributions to composite portfolios should be self-selected and include justification for the selection.
